Getting off topic I guess (since not really hypermiling), but I still think CNG is a better alternative than both hydrogen OR compressed air. The only downsides of CNG are decreased range (though still higher than the equivalent volume of Hydrogen or compressed air). CNG is FAR cheaper than Hydrogen. Natural Gas is already piped to a majority of homes in the United States, all that is required to fill your car at home is a small compressor. Natural Gas is a virtually raw product, limiting production costs. Natural Gas, unlike hydrogen or compressed gas, is actually an energy source - H2 and Air are just storage mediums.

Anyway, the cngchat site is a discussion group... There is a link to cngprices.com on there that is the station locater. Either way, I like driving my expedition around town on $1.27/gge fuel...

I agree storing hydrogen in cars is more work then needed. But what I'm talking about is storing water in your car, any water, and it's then filtered and the molecules are extracted. I've only seen this concept a few times but I think that would be optimum efficiency, all you need to do is find water and your good.

I think the consensus on that idea is that it requires more energy than you can extract as hydrogen. There are plenty of people who don't believe that the law of conservation of energy is real but I've yet to see them disprove it scientifically.

What is probably more likely is the reverse - a fuel cell that takes oxygen and hydrogen and generates electricity from them to power a set of batteries.

If you generate/compress the oxygen and hydrogen from wind or solar, it would be green. However, most hydrogen is derived from natural gas right now. Might as well just use the natural gas directly.

this concept is wron on many levels. You have to add energy to water molecules (a significant amount of it) to free the hydrogen bonds holding the molecule together. This energy is then returned when the hydrogen is allowed to rejoin the oxygen. This can be done in one of two ways. Combustion, where it returns the energy in the form of heat, or electolytic, where it is returned in the form of electric power. Either way, the conversion losses (which are basically waste heat) make it much less effiient than just using the natural gas to begin with.

As for making the hydrogen from wind or solar, you'd be better off using that electricity directly ni an electric battery vehicle.

There is no such thing as a water powered vehicle, and never will be, because there is no free energy to be found in water. Water is a relatvely stble, content molecule...one of the reasons there is so much of it on the planet. Once it is formed, it doesn't like to dissassociate.
